Czech declension describes the declension, or system of grammatically-determined modifications, in nouns, adjectives, pronouns and numerals in the Czech language. There is a system of 7 cases (nominative, genitive, dative, accusative, vocative, locative and instrumental) in Czech. Notice that no word has the maximum of 14 potential forms in singular and plural. Some forms are the same in more than one place in each paradigm.
